DPFF12D47J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF12D47J-F is a 4700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 1200V DC and 475V AC operation. This radial polypropylene metallized capacitor is designed for high pulse and DV/DT applications requiring through-hole mounting. The part is currently active in production with 1094 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements permit higher voltage ratings or different thermal specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF12D47J-F is determined by strict adherence to the following criteria:

Mandatory Match Parameters:

Capacitance: 4700 pF (exact match required)
Tolerance: ±5% (exact match required)
Dielectric Material: Polypropylene (PP), Metallized (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial (exact match required)
Lead Spacing: 0.720" (18.30mm) (exact match required)
Termination: PC Pins (exact match required)

Acceptable Variation Parameters:

Voltage Rating - DC: Substitute must equal or exceed 1200V
Voltage Rating - AC: Substitute must equal or exceed 475V
Operating Temperature Range: Substitute must support minimum -55°C to 105°C range (lower maximum temperature acceptable only if application permits)
RoHS Status: Must maintain ROHS3 Compliance

The substitute part 715P472516LD3 meets all mandatory match parameters and exceeds voltage ratings, making it a valid electrical substitute.

Engineering Selection Recommendations

Primary Part Selection (DPFF12D47J-F): Use the DPFF12D47J-F when the application requires the full operating temperature range of -55°C to 105°C and when the 1200V DC / 475V AC voltage rating is the design specification. This part is ROHS3 compliant and actively produced.

Substitute Part Selection (715P472516LD3): The 715P472516LD3 is a valid substitute when:

The application operating temperature does not exceed 85°C maximum
The higher voltage ratings (1600V DC / 500V AC) are acceptable or beneficial for design margin
PCB footprint and lead spacing requirements match (0.720" spacing confirmed)
The Orange Drop® 715P series characteristics are compatible with the application

Both parts are ROHS3 compliant, actively produced, and manufactured by the same supplier. The substitute provides higher voltage headroom at the cost of reduced maximum operating temperature.

Frequently Asked Questions (FAQ)

Q: Can the 715P472516LD3 be used as a direct replacement for the DPFF12D47J-F?

A: Yes, the 715P472516LD3 is a direct PCB replacement if the application maximum operating temperature does not exceed 85°C. All critical parameters including capacitance, tolerance, dielectric material, lead spacing, and mounting type are identical. The substitute provides higher voltage ratings, which is acceptable for applications designed for 1200V DC / 475V AC operation.

Q: What is the key difference between these two parts?

A: The primary differences are: (1) Operating temperature maximum: DPFF12D47J-F supports 105°C while 715P472516LD3 supports 85°C; (2) Voltage ratings: 715P472516LD3 has higher ratings (1600V DC / 500V AC vs. 1200V DC / 475V AC); (3) Series designation: DPFF vs. Orange Drop® 715P.

Q: Will the 715P472516LD3 fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing of 0.720" (18.30mm), radial package configuration, and through-hole mounting type. Physical dimensions differ slightly, but PCB hole pattern compatibility is confirmed.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPFF12D47J-F and 715P472516LD3 are ROHS3 compliant and REACH unaffected.

Q: Can I use the DPFF12D47J-F in applications requiring 1600V DC operation?

A: No. The DPFF12D47J-F is rated for 1200V DC maximum. Applications requiring 1600V DC operation must use the 715P472516LD3 or equivalent higher-voltage rated part.

Q: What happens if I use the substitute in an application requiring 105°C operation?

A: The 715P472516LD3 is rated only to 85°C maximum. Using it in applications requiring sustained operation above 85°C exceeds the part's specifications and may result in reduced reliability or failure. The DPFF12D47J-F must be used for applications requiring 105°C operation.
